201 Sov 20V Figure 13.3 4) See Figure 13.3. An oscilloscope screen produces the waveform shown. The vertical sensitivity control is set to 20 V/div, and the horizontal sensitivity is set at 100 us/div. What is the frequency of the displayed waveform? 1.25743 T= (8) (10yrs) = JOONS F gooμs=1.25KH) 4) 5) See Figure 13.3. An oscilloscope screen produces the waveform shown. The vertical sensitivity control is set to 20 V/div, and the horizontal sensitivity is set at 100 us/div. Write the general voltage equation that describes this waveform. 5) V(t)= 60 sim (211.25 kHz+= 0) 6) What is the phase relationship between voltage and current i if o-15 sin(yt +30°) and i-20 sin(yt-10°)? 6) MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 7) On an oscilloscope display: 7) A) voltage is on the vertical axis and time is on the horizontal axis. B) a flat horizontal trace means voltage is constant. C) a straight diagonal trace means voltage is changing at a steady rate. Dall the above 8) Determine the instantaneous value of a sine wave whose rms is 20 V, and phase angle is -297 degrees. 8) A)-17.8 V B)-25.2 V C) +25.2 V D) +17.8 V 9) What is the angular velocity of a phasor representing a sine wave with a frequency of 1.4 kHz?
